Comment # 12 on bug 1167132 from Andreas Schneider

If you don't have access to any Kerberos infrastructure you can use the one
from Fedora if you have a FAS account:

# cat > /etc/krb5.conf.d/fedoraproject >> EOF
[realms]
 FEDORAPROJECT.ORG = {
        kdc = https://id.fedoraproject.org/KdcProxy
 }
[domain_realm]
 .fedoraproject.org = FEDORAPROJECT.ORG
 fedoraproject.org = FEDORAPROJECT.ORG
EOF


$ kinit <user>@FEDORAPROJECT.ORG 
$ klist

In firefox you have to set in about:config

network.negotiate-auth.delegation-uris -> .fedoraproject.org
network.negotiate-auth.trusted-uris    -> .fedoraproject.org


If you have a ticket, e.g. visit https://bodhi.fedoraproject.org/
